Application of Customized Bootstrap CSS Not Successful

I have noticed that my custom CSS file does not override the bootstrap.min.css unless I include the !important tag in the class.

Specifically, when I try to change the color of my background header.

.bg-grey{
    background-color:#333 !important;
}

The following code, however, fails to alter the background color:

.bg-grey{
    background-color:#333;
}

Do you have any insights on why this is happening? I have placed the external stylesheet in the same directory as well.

Answer №1

One common reason for this issue is the parsing of bootstrap.min.css after your custom file. Have you checked the order in which you are including the css files in your head section? Make sure that your custom file comes after the bootstrap file to resolve this problem.

Answer №2

It is widely accepted to use !important for utility/helper classes, and the creators of Bootstrap have made the decision to apply the use of !important to all of Bootstrap 4's Utility classes.

The background color utility classes (bg-*) utilize !important, therefore any custom color overrides must also include !important to take precedence.

Nevertheless, please note that bg-grey is not a predefined color in Bootstrap 4. When defining a custom color, ensure that your overrides are consistent with any previous CSS definitions related to bg-grey.
